FOUNTAIN PEN AND ELECTRIC LIGHT.

Application filed June 12, 1923. Serial No. 844,948.

To all whom it may concern:

Be it known that I, JOHN JOSEPH DEVINE, a citizen of the United States residing at Middletown, in the county of Middlesex and State of Connecticut, have invented certa n new and useful Improvements in Fountaln Pens and Electric Lights, of which the following is a specification.

The invention relates to improvements in fountain pens, and has for one of 1ts ob ects to provide a device of this character, having an electric lamp enclosed 1n the barrel thereof and to illuminate the paper being written on in the immediate vicinity of the pen point, to enable the pen to be employed at night or in dark locations.

Another object of the inventlon is to provide a device of this character having an 1mproved construction of the switch whereby the light is coupled to the source of electrlc energy.

Another object of the invention 1s to provide a device of this character formed in separable parts to facilitate the renewal of impaired parts.

With these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims, and in. the drawings illustratlve of the preferred embodiment of the invention.

Figure 1 is a longitudinal section of the improved device.

Fig. 2 is a transverse section on the l1ne 22 of Fig. 1, looking in the direction of the arrow.

Fig. 3 is a transverse section on the line 3-3 of Fig. 1, looking in the direction of the arrow.

Fig. 4 is a transverse section on the line 4-4 of Fig. 1, looking in the direction of the arrow.

Fig. 5 is a transverse section on the line 5-5 of Fig. 1, looking in the direction of the arrow.

Fig. 6 is a transverse section on the line 6-6 of Fig. 1, looking in the direction of the arrow.

Fig. 7 is a perspective view of the improved device.

Fig. 8 is a perspective view of the part of the barrel of the pen viewed from the upper end, together with the combined hood or pen point protector and the switch operating key.

F 9 is a side view of the combined pen point socket and feed tube carrier.

Fig. 10 is a detached perspective view of the lamp socket and jumper holder.

Fig. 11 is a side elevation of the pen point portion of the implement with the point hood or cover in longitudinal section.

The improved device comprises a metal barrel or stock, represented as a whole at 10 and having an externally threaded metal cap 11 at one end. Disposed within the barrel 10 is a suitable small storage battery, represented conventionally at 12, and of less length than the barrel.

Fitting within the barrel 10 at the end opposite to the cap 11, is a tubular metal member 13, the latter extending at its forward end in advance of the member 10 and the outer portion converging as shown at 14 to cause a condensation of the light rays as hereafter explained. The converging portion is also provided with recesses or cavities 15 at the opposite sides to permit the lateral diffusion of the light rays as hereafter explained.

The member 13 is coupled to the barrel 10 by clamp screws 16.

Fitting within the member 13 is a combined ink reservoir and pen point socket holder comprising a hollow crescent shaped inner portion 17 and a hollow semi-cylindrical portion 18, and a smaller hollow pen point receiving portion 19, with an ink duct 20 providing communication between the portions 18 and 19.

The combined ink reservoir and pen point socket is supported within the member 13 by braces 21, as shown in Figs. 1 and 2.

The pen point socket is represented as a whole at 22, and fits closely in the holder portion 19, and is formed with an encircling channel to receive a packing ring 24 of rubber or the like, operating to engage the interiorof the holder 19 to frictionally hold the socket in position and also prevent leakage of ink from the reservoir. The socket 22 is provided with a lateral flange 23 forming its outer end, and provided with a socket to receive the pen point represented at 25. Extending from the closed end 23 of the holder 22 is the ink conductor tube 25 which terminates adjacent the inner face of the pen point 25*, as shown.

Fitting within the crescent shaped portion 17 and bearing therein by its upper part is a metal lamp socket receiver 26. and bearing by its lower part upon the inner face of the niember 13 as shown by Figs. 1 and 4. The interior of the member 26 is threaded to receive an electric light lamp socket represented conventionally at 27, the threaded cavity being inclined to the longitudinal axis of the member 26, so that the center line of the bulb, represented at 28, is directed toward the outer end of the pen point, as indicated by the broken line 29.

By this arrangement the lamp 1s located below the lower line of the pen point and its rays directed obliquely to the longitudinal axis of the same, and practically eliminating shadows around the pen point while writing. The lateral recesses 15 also ermit the light rays to be disseminated liiterally, and thus illuminate a larger area at each side of the pen point, and upon a larger area of the surface being written on.

This ability to throw the light rays to the pen point is an important advantage and materially increases the efliciency and utility of the implement.

Fitting over the projecting portion of the member 13 is a hood or cover 30 for the pen point, the hood having a key member 31, projecting from its outer end, the ob ect to be hereafter explained.

Formed upon the inner end of the lamp socket receiver 26 is a socket device 32 In which a resilient bendable metal jum er member 33 is supported and insulate as shown at 34 from the socket 32. The member 33 depends below the line of the contact element 35 of the lamp socket, and is normally in contact therewith as shown in Figure 1. The core member 36 of the battery within the shell 12 bears against the jumper member 33, as shown in Fig. 1.

The inner portion of the cap 11 1s formed with an annular cavity 37,- and inwardly directed stop lugs 38 projecting into the cavity, thus forming diagonally opposite seats to receive the ends of a cross bar 39, of rubber or other nonconductive material with a bearing plate 40 riveted as shown at 42 to the bar 39. A coiled spring 43 is attached at one end to the plate 40 and extends between the plate and the adjacent end of the battery shell 12.

The cap 11 is formed with a central threaded opening to receive a threaded plug 44, the latter having an inner flange 45 hearing against the bottom of the cavity 37 and with an outwardly opening socket 46 to receive the key 31 of the hood 30.

The lug 44 constitutes the controlling switch by which the circuit is closed and broken through the battery within the shell 12.

When the plug 44 is in its outer position as shown in Fig. 1, the rivet contact 42, plate 40 and spring 43 remain in inoperative position as shown in Fig. 1 or with the circuit through the storage battery broken, and the light out out. If the light is required, the hood 30 is detached and the key end 31 inserted in the socket 46 and the plug rotated to cause the flange 45 to contact with the rivet 42 and thus close the circuit through the battery within the shell 12, the battery core 36, the jumper 33, lamp 28, receiver 26, shell 13, barrel 10, cap 11, plug 46, rivet 42, plate 40, spring 43 to the battery again, and thus close the circuit therethrou h, which will remain lighted so long as tie plug 44 remains in its inner osition.

When the writing is comp eted, the key 31 is again inserted in the lug and the latter reversely rotated to isconnect the flange 45 from the rivet or contact 42 and thus break the circuit through the lamp.

The improved device may be constructed of an required size and of an required material, and it is not desire to limit the invention in any manner in this respect.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be understood that modifications within the scope of the claims may be made in the construction without departing from the principle of the invention or sacrificing any of it advantages.
